摘要
We prove that any polyhedron of genus zero or genus one built out of rectangular faces must be an orthogonal polyhedron, but that there are nonorthogonal polyhedra of genus seven all of whose faces are rectangles. This leads to a resolution of a question posed by Biedl, Lubiw, and Sun [BLS99].

19 pages, 20 figures. Revised version makes two corrections: The statement of the old Lemma 14 was incorrect. It has been corrected and merged with Lemma 13 now. Second, Figure 19 (a skew quadrilateral) was incorrect, and is now removed. It played no substantive role in the proofs
